OVERTURN PREVENTING DEVICE AND WORK MACHINE
To prevent overturn of a work machine, considering a danger of collapse in ground surface around a work machine.SOLUTION: A region setting section 253 detects a collapse danger region based on distance image data of terrain around a work machine 1 measured by a distance measuring sensor, and moves: at least sides interposed between the collapse danger region and a center of a support polygon among four sides constituting a warning line B1; and at least sides interposed between the collapse danger region and a center of a support polygon among four sides constituting a control line B2, respectively toward the center of the support polygon. An overturn preventing control portion 254 warns to notify a danger of collapse when a center of gravity G is positioned outside of the warning line B1, and performs an overturn preventing control when the center of gravity G is positioned outside of the control line B2.SELECTED DRAWING: Figure 3
【課題】作業機械の周囲の地面の崩落の危険性を考慮に入れて作業機械の転倒を防止する。【解決手段】領域設定部２５３は、測距センサで計測された作業機械１の周囲の地形の距離画像データから崩落危険領域を検出し、警告線Ｂ１を構成する４辺のうち少なくとも崩壊危険領域と支持多角形の中心とに介在する辺と、制御線Ｂ２を構成する４辺のうち少なくとも崩壊危険領域と支持多角形の中心とに介在する辺とのそれぞれを支持多角形の中心方向に移動させる。転倒防止制御部２５４は、重心Ｇが警告線Ｂ１よりも外側に位置する場合、転倒の危険性を報知するための警告を行い、重心Ｇが制御線Ｂ２よりも外側に位置する場合、転倒防止制御を行う。【選択図】図３
